Reflection and refraction of a plane wave at the interface of double negative and double positive media
平面波在雙負和雙正參數媒質界面的反射與折射 -
It is demonstrated that the transmission becomes tunable, depending on the thickness and the refraction index of the slabs deeply : as the thickness of lhm slab in the structure becomes wider, the bragg gap shifts toward higher frequency, in sharp contrast to its shift toward lower frequency as a result of widening the thickness of positive - index - material slab
然後利用傳輸矩陣法理論分析了這種結構的傳輸特性，證實了新帶隙的存在，同時發現結構的傳輸特性與結構組成介質的厚度以及折射率密切相關，當正折射物質的厚度增加時，傳統bragg帶隙會沿頻率軸向低頻方向移動，若為左手物質則向高頻方向移動。 -
